A few 6max hands.

1. AA, bad river.

The table has been loose and passive and I've been running it for the past 20 minutes - hitting draws but not getting my riverbets called. Opp is a relative newcomer but doesn't seem to have broken the LP mode that the rest of the table is stuck in.

Are my value bets sub-value, especially considering the board pair? Is this a river call or can I get away from it?

2. Button limp-special. Same session.

BB is LP and has seen me use and abuse position throughout.
SB is very very very very tight and passive. Weakish postflop.

Is this hand worth stacks on the flop?

Your bets are SO weak. 2.5 into a 6 dollar pot? How about 4.5, then 10 on the turn. Your bets are giving people correct odds to draw as well as are asking to be raised. Put some muscle in your betting, please.

Hand 1. Raise more pre-flop. Bet more on flop. Bet more on turn.

Hand 2. Fold.
